Advent of Code in Typescript

This is a simple framework for solving Advent of Code (aka AoC) puzzles using Typescript. To use it for your solutions, fork this project on GitHub so that you can share your solutions.

Every day, AoC publishes a new puzzle in 2 parts. The second part is only accessible once you solved the first part. Together with the puzzle, AoC provides a user-specific input file for the puzzle. Thus, this repo has a separate directory for each day which contains both the input file and the solution code. The solution code uses simple unit tests for executing the code and capturing the expected answer. Thus, to solve a new puzzle, follow the below instructions by replacing 2022/Day02 with the correct year and day:

1. Copy the Template directory to 2022/Day02
2. Download the input file the day and store it in 2022/Day02/input
3. Add your solution for part 1 to 2022/Day02/solution.ts
4. Submit the correct answer for part 1 to AoC
5. Repeat steps 3 and 4 for part 2
6. Enjoy!

Setup

Make sure to have a recent NodeJs version installed (version 16 or higher), and run npm i. Also sign up for AoC to get access to the personalized puzzle inputs.

This repo contains the solution for day 1 of 2022 for a personal input file. Thus, to get your 2 gold stars for that day, you must

1. Download your input for day 1 and replace the content of 2022/Day01/input with your downloaded data
2. Run the tests of 2022/Day01/solution.ts, which will very likely fail due to the updated input
3. Replace the expected results with the actual results to fix the tests
4. Enter the results on AoC
5. You got your first 2 gold stars!!!

Command line execution

Running npm test will execute all the existing tests.

IDE support

IntelliJ

For IntelliJ Ultimate, the built-in debugging support should allow to directly execute and debug individual tests.

VS-Code

For VS-Code, you should first install the Jest (by Orta) extension from the official Vs-Code extension marketplace.
